Compared with ordinary wire drawing dies, cobalt based polycrystalline diamond has higher hardness, better wear resistance, more uniform inner hole wear, stronger impact resistance, and larger wire drawing amount,
The high wear-resistant cobalt based die has good and extensive processing performance. The random and free arrangement of diamond micro particles in the die blank makes the wear uniform and can ensure the roundness of the wire drawing.
The polycrystalline diamond cobalt-based die blank is manufactured by the advanced hpht process, which can meet the high-speed drawing of stainless steel, copper, aluminum and other alloy wires.
